LUBRICATING DEVICE.

Specification of Letters Patent.

Patented July 16, 1918.

Application led August 11, 1917. Serial No. 185,665.

To all 'whom it may concern Be it known that we, (1) JOHN C. SWAY- KUs and (2) ALEX TKAcz, (l) a citizen of the United States, (2) subject of the Emperor of Austria, residing 4at Lackawanna, in the county of Erie and State of New York, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a specification.

This invention relates to certaiirnew and useful improvements in lubricators of that class in which lubricant is continuously fed from a stationary oil-cup to a rapidly mov ing part of a machine, such as a crank pin.

Heretoforc each lubricator of this'typc had to be specially constructed for and carefully adjusted to the. particular machine with which it was to be used,- as no support for the oil-cup 'was devised to accommodate for the varying cthrowsf of 'diiferentsized' and shaped crank-pins of di'erentmachines.

It is the especial object 'of the present-invention to provide a `supporting structure for the oil-cup of this type of lubricator, whereby the same may be secured to a machine without predetermining the exact point where the same should be, in operation, and whereby the same may be subsequently7 easily and quickly adjusted to such point.

A further object is to insure a proper discharge of the lubricant upon the crank pin. With these general objects in view and others that will be apparent as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully de scribed, illustrated in the accompanying drawings and then claimed.

In the drawings forming a part of this a plication and in which like designating c aracters refer to corresponding parts l throughout the several views,

Figure 1 is a side elevation of a portion of an engine with the present invention in its o erative osition thereon, one of the fly w eels of tile engine being removed.

. Fig. 2 is a plan vlew of the device shown in F1g. 1.

Fig. 3 is an enlarged detail view, partly in vertical section, showing the pivotal con nection between the inner conveying tube and the bracket.

Fig. 4 is a view similar to Fig. 3, taken at right angles thereto.

Fig. 5 is an enlarged detail view, partly in vertical section, of the crank-pin and parts associated therewith.

Fig. 6 is a vertical sectional view of the parts shown in Fig. 5, taken at right angles to the' plane of section thereof,l and Fig. is an end elevational viewof the device, the engine pitman being in vertical section and parts being broken away, an adjustment of certain parts being shown by dotted lines.

In carrying out the present invention, a post 5 is vertically secured to one side of the engine base 6 by any suitable means such as a plate 7 and bolts 8, see Fig. 2. This post is preferably hollow and vertically slidable therein is a rod 9 held in adjusted. positions by a set screw 10. The upper end of the rod 9 is provided with a transversely positioned tubular portion 1l and slidable therein transversely of the engine frame is another rod 12 held in adjusted positions by a set screw 13. The inwardly extending end of the rod 12 is provided with a tubular portion 14 and slidable therein for adjustment longitudinally of the engine frame is a rod 15 held in adjusted positions by a set screw 16.

An oil-cup 17 of any suitable design is suitably secured to the end of rod 15 which extends to a point above and adjacent the crank shaft 18 and the outlet neck 19 of said cup is positioned so that the port therein registers with a passage 20 through the rod 15 which may be provided with a suitable valve 21 to control the flow of lubricant `therethrough. LJScrewed into the passage 2O E@iss alfshort pipe 22 whose lower end is provided with a cylindrical enlargement 23 and whose passage is enlarged as at 24. A two` part member 25, whose complementary formed sections are secured together by bolts 26, is provided with a socket 27 to pivotally receive the cylindrlcal enlargement 23 and said member 25 is provided with a slot or enlarged opening 28 to rovide a clearance for the pipe 22 when the member 25 is oscillated relative thereto. A passage 29 is formed in the member 2 5 and the upper portion of this passage .is enlarged as at 30 so that at no time will the passage 24 be closed and the drops of lubrlcant will be directed upon the face of the passage at the portion 30 as shown at 31 1n 1 3. rghe member 25 is screwed or otherwise secured' in a section of ipe"32 which' isvnslidably telescoped into a ightly largerusectiqn of pipe 33 which is screwed onto a shortY lipe 34 similar to" the pipe 22 and Whose ciindricel enlarged portion 35 is pivotally received by the socket 36 of a two-part meniber,37 ,as shown in Fgs. 5 and 6. The-com plementary 'formed sections of member 37 are suitably secured together, as byfbflts 38, and the same is provided with u slot or enlerg-ed-opening 39 to provide@ eleereneefor the pipe 34: when the same is; oscilleted reletive thereto.

rPhe crank shelft 18 is suitably journaled in brackets 4'() upontbebase 6 amd is provided with a cra/nk 41 whose crank pin 42 is provided with two grooves 43 Whfieh are spaced end each of which extend approximately half way around ehe cireumvfference of the pin. The pitman 44 is provided with a wrist or coller whose two members 45 and 46 are secured together by bolts 47. The upper meeting feces of these members 45 and 4-6 are provided with ro'oves 48, enlly ene of which registers witi a groove 43 et a time sind both of which are in censterrt oom.- municetiofn with the passage@ in the pipe 34 through vopenings 56) in the member 3?? which is secured to the wrist er collar members by-meens of screws 541.

In Fig. 7, We have illustrated in :dotted lines the utility of providing .-the'vertioal'adjustment of rod 91t0 accommodate the M1- bricetor or stationary parts shhereoif te the varying throws of cranks of different m'a.- chi-nes, it being obvious that the lenger the crank is, the greater the distance is Uhatfthe oil-@urp must be supportedY above thelbase' 6.

VVhen the parts aire im assembled relaftion, the pest 5 is secured to the base 6 amd rthe mds l2 and 15 are quickly adjustedwte beitien the eil-emp above amcjeeent` and mii Waiy between the ends ef :the pin F42, thus easily obtaining a preper alfinement of che panas; as

When AtLlivewengfine is in operation the valve 21 may be Opened and thelubriantellowed to flow therefrom totliel ports"4"8"and et every revo- .lutiqnef the crank shaft the grooves are alternttely'filled with lubricant. which seeps out and ,thus most effectively distributed overthe crank pin.
